GraphViz - Nodes stack to the right


in order to visualize the mentor-student relations inside my fraternity, I'd like to create a genealogy graph from a Excel spreadsheet. This works way better than expected, but there is one final issue. To demonstrate, this is a smaller version of the graph:

It is ordered by year (to the very left), while members are placed in the appropriate timeslot and are connected to show said relations.

Unfortunately, as you can see, during a few years when the choosing of mentors was partly suspended due to historical reasons (WWII etc.), the members stack up to the right of the graph, widening it a lot.

Is there a way to specify that they are supposed to be distributed among the members that are part of the structure in order to achieve minimum width? I would be very grateful, as the graph is to be printed for our 145th anniversary, and the current layout just looks ugly.

Thanks for helping,

One option (which I haven't tried, so this is a guess) might be to encapsulate the offending chunk as a subgraph and specify separate properties for that subgraph.

A more tedious alternative is to run dot without arguments to get dot-type output, in which each node has a pos="X,Y" attribute added.
Then use your favourite editor to adjust the X,Y values of the offending nodes, and re-run dot using -n2 to stop it using a layout engine to
move the nodes around.

There must be other ways too?
